JERUSALEM (AP) — After 800 years of silence, a pipe organ that researchers say is the oldest in the Christian world roared back to life Tuesday, its ancient sound echoing through a monastery in Jerusalem’s Old City.

Composed of original pipes from the 11th century, the instrument emitted a full, hearty sound as musician David Catalunya played a liturgical chant called Benedicamus Domino Flos Filius. The swell of music inside Saint Saviour’s Monastery mingled with church bells tolling in the distance.

Before unveiling the instrument Monday, Catalunya told a news conference that attendees were witnessing a grand development in the history of music.

“This organ was buried with the hope that one day it would play again,” he said. “And the day has arrived, nearly eight centuries later.”

From now on, the organ will be housed at the Terra Sancta museum in Jerusalem’s Old City — just kilometers (miles) from the Bethlehem church where it originally sounded.

Researchers believe the Crusaders brought the organ to Bethlehem, the birthplace of Jesus, in the 11th century during their period of rule over Jerusalem. After a century of use, the Crusaders buried it to protect it from invading Muslim armies.

There it stayed until 1906, when workers building a Franciscan hospice for pilgrims in Bethlehem discovered it in an ancient cemetery.

Once full excavations were conducted, archaeologists had uncovered 222 bronze pipes, a set of bells and other objects hidden by the Crusaders.

“It was extremely moving to hear how some of these pipes came to life again after about 700 years under the earth and 800 years of silence,” said Koos van de Linde, organ expert who participated in the restoration. “The hope of the Crusaders who buried them — that the moment would come when they would sound again — was not in vain.”

A team of four researchers, directed by Catalunya, set out in 2019 to create a replica of the organ. But along the way, said Catalunya, they discovered that some of the pipes still function as they did hundreds of years ago.

Organ builder Winold van der Putten placed those original pipes alongside replicas he created based on ancient organ-making methods, some of which were illuminated by close study of the original pipes. The originals, making up about half of the organ, still bear guiding lines made by the original Ottoman craftsmen and engraved scrawls indicating musical notes.

Alvaro Torrente, director of the Instituto Complutense De Ciencias Musicales in Madrid — where Catalunya undertook the project — compared the discovery to “finding a living dinosaur, something that we never imagined we could encounter, suddenly made real before our eyes and ears.”

Researchers hope to finish restoring the entire organ and then create copies to be placed in churches across Europe and the world so its music is accessible to all.

“This is an amazing set of information that allows us to reconstruct the manufacturing process so that we can build pipes exactly as they were made,” about a thousand years ago, said Catalunya.

CUPERTINO (AP) — Apple on Tuesday will unveil its next line-up of iPhones amid a global trade war that’s added a potential price increase to the usual intrigue surrounding the annual evolution of the company’s marquee product.

The new iPhones will be the first to be released since President Donald Trump returned to the White House and unleashed a barrage of tariffs, in what his administration says is an attempt to bring overseas manufacturing back to the U.S. — a crusade that has thrust Apple CEO Tim Cook into the hot seat.

If Apple follows the same naming scheme since the product’s 2007 debut, the new models will be called the iPhone 17. But the Cupertino, California, company recently deviated from tradition with its naming formula for the iPhone operating system. When the next version of its iOS system was previewed at its developers conference in June, Apple revealed the free update will be called iOS 26 in reference to the upcoming year — a marketing technique that automakers have embraced for decades.

Regardless, these new iPhones are still expected to be made in Apple’s manufacturing hubs in China and India, much to the Trump administration’s consternation.

Both Trump and U.S. Commerce Secretary Howard Lutnick have repeatedly insisted that iPhones be made in the U.S. instead of overseas. It’s an unrealistic demand that analysts say would take years to pull off and would result in a doubling, or even a tripling, of the iPhone’s current average price of about $1,000.

Cook tried to placate Trump by initially pledging that Apple would invest $500 billion i n the U.S. over the next four years, and then upped the ante last month by adding another $100 billion to the commitment. He also gifted Trump a statue featuring a 24-karat gold base.

That kind of diplomacy has helped insulate Apple from Trump’s most severe tariffs. However, the iPhones being brought into the U.S. still face duties of about 25%, stoking speculation that the company will reveal its first across-the-board price increase in five years in an effort to preserve its hefty profit margins.

Since 2020, Apple has charged $800 for its basic iPhone and $1,200 for its top offering, but analysts now believe the company may raise prices by $50 to $100 on some of the new models. If Apple does announce price increases, it will come just weeks after Google held steady on prices for its new Pixel smartphones.

Whatever Apple ends up charging for the next iPhone, the new line-up isn’t expected to be much different from last year’s model — the first to be designed for a wide range of new artificial intelligence features. While the iPhone 16 has proven to be popular, the models didn’t sell quite as well as analysts had anticipated because Apple failed to deliver all the AI-fueled improvements it had promised, including a smarter and more versatile Siri assistant. The Siri improvements have been pushed back until next year.

That has lowered the expectations for this year’s line-up, which will likely include the usual improvements in camera quality and battery life on top of a slightly redesigned appearance. The most significant new twist could be the introduction of an ultra-thin iPhone dubbed “Air” — a moniker Apple already slaps on like its sleekest iPads and Mac computers.

The relatively minor updates to recent iPhone models are raising questions about Apple’s ability to innovate in the fast-moving era of AI, said Forrester Research analyst Thomas Husson. “Apple is reaching a tipping point, and I expect 2026 and 2027 to be pivotal years.”

Apple’s AI follies, combined with its exposure in Trump’s trade war, have weighed on the company’s stock, while the market values of Big Tech peers like Microsoft, Nvidia, Meta Platforms and Google parent Alphabet have been surging.

Although Apple’s stock price is still down by 4% so far this year, the shares have been bouncing back in recent months amid signs it won’t be as hard hit by the tariffs as once feared, and a highly anticipated court ruling cleared the way for the company to continue receiving $20 billion annually to lock in Google’s search engine as the default option on iPhones.
